11 Measurements and Adjustments
This chapter explains the measuring equipment, the JIG connection, and the PC setting method necessary for the measurement in
Troubleshooting Guide (P.23)
Troubleshooting Guide (P.23)
11.1. Equipment Required
• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope.
• Frequency counter: It must be precise enough to measure intervals of 1 Hz (precision; ±4 ppm)
• Oscilloscope.
• Frequency counter: It must be precise enough to measure intervals of 1 Hz (precision; ±4 ppm)
Hewlett Packard, 53131A is recommended.
• DECT tester: Rohde & Schwarz, CMD 60 is recommended.
This equipment may be useful in order to precisely adjust like a mass production.
11.2. The Setting Method of JIG (Base Unit)
This section explains the PC setting to use command required in Check Point (Base Unit)(P.35).
<Preparation>
• Serial JIG cable: PQZZ1CD300E*
• PC which runs in DOS mode
• Batch file CD-ROM for setting: PNZZTG5511RU
• PC which runs in DOS mode
• Batch file CD-ROM for setting: PNZZTG5511RU
Note:
*: If you have the JIG Cable for TCD500 series
(PQZZ1CD505E), change the following values of
resistance. Then you can use it as a JIG Cable for both
TCD300 and TCD500 series. (It is an upper compatible JIG
Cable.)
resistance. Then you can use it as a JIG Cable for both
TCD300 and TCD500 series. (It is an upper compatible JIG
Cable.)
11.2.1. Connections
Connect the AC adaptor to DC-JACK (base unit).
Connect the JIG Cable GND (black) to GND.
Connect the JIG Cable RX (red) to URX and TX (yellow) to UTX.
Connect the JIG Cable GND (black) to GND.
Connect the JIG Cable RX (red) to URX and TX (yellow) to UTX.
Note:
*: COM port names may vary depending on what your PC calls it.

Note:
• “*****” varies depending on the country or models.
11.2.3. Commands
See the table below for frequently used commands.
1.
Insert the Batch file CD-ROM into CD-ROM drive and
copy PNZZTG**** folder to your PC (example: D drive).
2.
Open an MS-DOS mode window.
3.
At the DOS prompt, type "D:" (for example) to select the
drive, then press the Enter key.
4.
Type "CD
㪳PNZZTG****", then press the Enter key.
5.
Type "SET_COM=X", then press the Enter key
(X: COM port number used for the serial connection on your PC).
6.
Type "READID", then press the Enter key.
䊶If any error messages appear, change the port number or
䇭check the cable connection.
䊶If any value appear, go to next step.
7.
